Concentric Flue System- Type K
Horizontal concentric flue kit Ø60/100 mm polypropylene inner pipe.
Adjustable through 360°.Discharges exhaust fumes an d draws air from atmosphere.
Suitable
for
condensing
boilers
only.
Discharges
exhaust
gases
and
draws
combustion air by means of two concentric
ducts. The external Ø100 duct draws the
combustion air while the Ø60 plastic inner duct
discharges the exhaust fumes.
The discharge duct can be terminated directly
to the outside or can be connected to a suitable
plume management system.
MAXIMUM FLUE LENGTH : 6 m
The maximum flue length (linear equivalent)
is obtained by totalling the length of linear
pipe and the equivalent lengths of each
bend fitted.
The linear equivalent is intended as being the
total length of the duct from the connection with
the combustion chamber of the appliance,
excluding the first bend.
The linear equivalent of additional bends is
as follows:
Ø 60/100 x 90° bend = 0.8 m.
Ø 60/100 x 45° bend = 0.5 m.
